BYRON PHELPS, OF SEATTLE, WASHINGTON.

LOCK.

SPECIFICATION forming part of Letters Patent No. 722,621, dated March10, 1903.

Application filed September 23, 1901. Serial No. 761312. (No model.)

T0 at whom it may concern.-

Be it known that I, BYRON PHELPS, a citizen of the United States,residing at Seattle, inthe county of King and State of Washiugton,haveinvented a new and useful Look, of which the following is aspecification.

My invention relates to looks, and particularly to a lock having a framewhich carries all of the mechanism and which is adapted to be insertedin a notch in the stile of a door.

Particularly it relates to improvements in the mechanism for locking theouter knob from the face of the lock and in providing a simple andelfective device for holding the spindle in place.

Figure l is a plan view. Fig. 2 is an end View of a portion of the lock,partly in section. Fig. 3 is a view of the face, on a reduced scale.Figs. 4. 5, 6, 7, and 8 modetails.

A is a frame. B B are extensions therefrom in the form of sleeves, whichprovide suitable bearings for an inner spindle O and an outer spindle 0.Attached to spindle O is an inner knob D, while attached to spindle C isan outer knob D.

E is-a latch-bolt pivotally secured to the frame A.

F is a yoke one end of which is connected with the latch-bolt E, whileits other end straddles the inner ends of the spindles O O. The end ofspindle C is notched, and fitted therein is a roll-back G. (See Fig. 5.)The inner end of spindle O is likewise notched and carries a roll-backG.

The outer knob D is hollow and houses a key mechanism H. This keymechanism may be of the well-known pin-tumbler type and will not beparticularly described.

J is a key-rod passing through the center of spindle C, one end beingattached to the key mechanism, while its other end is fitted to a squarehole in roll-back G. The rollback G has a central opening sufficientlylarge to allow rodJ to turn freely. When either spindle is rotated, itsattached rollback bearsagainst and moves the yoke F, thereby retractingthe latch-bolt E.

K is a spring for returning and holding the latch-bolt E in its extendedposition.

The spindle C has a hole L near one end.

M is a pin slidably mounted in the frame A and adapted to enter the holeL, and thus lock the spindle C from rotation.

N is a finger-lever pivoted to the frame A and lying in an opening inthe face of the frame.

0 is a strap connecting the finger-lever N and the pin M.

.When it is desired to lock the outer knob, the finger or thumb ispressed against the flush end of the lever N, which rocks the same,thereby moving the strap 0 and pushing the pin M into the hole L. Theparts then take the position shown in dotted lines in Fig. 1. The innerknob D is free to be turned by any one on the inside of the door, theouter knob being locked obviously.

In order to retract the latch-ebolt-from-the outside, a key must beinserted in the mecheffii'sTrTHand then turned. The roll-back G beingrocked by the rotation of rod J, movement is imparted to yoke F and thelatch bolt E retract-ed I P is a flat spring which takes into notches RR in the strap 0 and prevents the pin from being jarred from position.

The spindle O has a segmental slot near one end, as shown.

T is a pin one end of which is flattened, as shown in Fig. 7, and iscarried in the frame A, the flattened portion projecting into the slotand its flat face bearing against the innor edge of the slot, thusholding the spindle C in longitudinal position. The opposite spindle 0has a similar slot S and pin T.

One method of holding the pins T T, I have shown in Fig. 8.

U U are light springs which may be fastened to the frame, their freeends lying in notches in pins T T. This construction allows of the readyremoval of the spindles and knobs. A further advantage is that should apin or slot become worn a new pin may be fitted to take up the wear.

It is obvious that many changes might be made in the construction hereinshown without departing from the spirit ofthe invention. For instance,the lever N might lie inside the frame and have a push-button for eachend extend through and lie fiush'with the face. Other changes willreadily sug- ICO gest themselves to one skilled in the art, and Ido not,therefore, li-mit myself to this specific construction.

What I claim is 1. In a look, a frame, a latch-bolt, a spindle,aconnection between said spindle and said latch-bolt, a finger-lever inthe face of the said frame and a connection from said lever to saidspindle, said connection being in detachable engagement with saidspindle.

2. A frame, a latch-bolt, a spindle, a connection between said spindleand said latchbolt, a finger-lever pivoted in the face of said frame, aslidable pin adjacent said spindle, a strap connecting said lever andsaid pin, and means carried by said spindle which cooperate with saidpin to hold said spindle from rotation.

3. A frame, a latch-bolt, an outer and an inner spindle, meansconnecting said outer spindle with said latch-bolt, means connectingsaid inner spindle with said latch-bolt, a finger-lever in the face ofsaid frame, a connection from said lever to said outer spindle, keyoperated means passing through said outer spindle and engaging with saidsecondnamed means whereby said latch may be operated by saidkey-operated means.

4. A frame, a latch-bolt, an outer and an inner spindle, meansconnecting said outer spindle with said latch, means connecting saidinner spindle with said latch, a fingerlever in the face of said frame,a'slidable pin adjacent said outer spindle, a strap connecting saidlever and said pin, means carried by said outer spindle which cooperatewith said pin to hold said outer spindle from rotation, and key operatedmeans passing through said outer spindle and engaging with said secondnamed means, whereby said latch may be operated by said key-operatedmeans.

5. A frame, a spindle having a transverse slot therein, a pin carried bysaid frame and projecting into said slot, said pin having onebearing-face lying against one edge of said slot to hold said spindlefrom longitudinal play, and a shoulder on said pin forming anotherbearing-face which rests upon the outer surface of said spindle, to holdsaid spindle from lateral vibration. I

6. A frame, a spindle having a transverse slot therein, a pin removablycarried by said frame and projecting into said slot, said pin having onebearing-face lying against one edge of said slot to hold said spindlefrom longitudinal play, and a shoulder on said pin forming anotherbearing -face which rests upon the outer surface of said spindle, tohold said spindle from lateral vibration.

7. A frame, a spindle having a segmental slot therein, a pin removablycarried by said frame and projecting into said slot, and a springcarried by said frame and bearing against said pin.

8. A frame, a spindle having a segmental slot therein, a pin removablycarried by said frame and projecting into said slot, and a spring oneend of which is attached to said frame the other end engaging a notch insaid in. p 9. A frame, alatch-bolt and latch mechanism for operatingsaid latch-bolt, a fingerlever in the face of said frame, saidfingerlever having two exposed faces, the plane of one face beinginclined to the plane of the other face, and means connected to saidfinger-lever, movable into engagement with said latch mechanism.
